While I don’t know the answer and if no one else answers, it might depend on whether you’re fitting the pipes or having the dealer do it. 

Tony, I think you have mid controls, the bikes that have them forward have forward control's, personal I like mid controls. you could fit those pipes and make the pillion pegs fit

Have a look at lets see your sporty in sportster section & you see heeps of photos with sideshots both forward & mid mounted controls

Thanks for your help guys
